Using HeishaMon without any home automation

[HighlyCompressedAir]

Hi, I don't have any home automation setup and I'd like to use HeishaMon to control my HP by itself using rules functionality and I have a few questions:

1. Does HeishaMon support automatic summer/winter time change? HP controller doesn't and it's annoying.
2. Is it possible to use actual time in rules? I'd like to create a schedule to heat water during cheap electricity hours because of reason nr 1. Also the HP controller doesn't keep the time very well and it becomes more and more inaccurate overtime.
3. Does HeishaMon PCB keeps it's logs anywhere? I assume they just exist in memory and get wiped out after power loss? How big these logs can get? I'd like to download them on my PC and turn the data into nice graphs just like Panasonic Service Cloud does. Readme mentions this url - http://heishamon.local/json Can you show me a screenshot so I can see how does it actually look like?

Thank you.
